Understanding Low Vision

Low vision is a condition where a person has a significant visual impairment that cannot be fully corrected with glasses, contact lenses, or surgery. It often interferes with daily activities due to the inability to clearly see objects, read, and recognize faces. In this section, we will discuss the causes of low vision and the different levels of vision loss.

Causes of Low Vision

There are several eye conditions and diseases that can lead to low vision. Some common causes include:

• Age-related macular degeneration (AMD): This is one of the most common causes of low vision in older adults. AMD occurs when the macula, which is responsible for central vision, becomes damaged.
• Glaucoma: This eye disease involves damage to the optic nerve, often due to increased pressure in the eye. Glaucoma can cause visual field loss and, if left untreated, can lead to blindness.
• Diabetic retinopathy: This condition is a complication of diabetes and occurs when the blood vessels in the retina are damaged. Diabetic retinopathy can cause vision loss and, in severe cases, blindness.
• Cataracts: A cataract is the clouding of the eye’s natural lens. This can cause blurry vision and difficulty seeing in low light conditions. Cataracts are often age-related and can be treated with surgery.
• Retinitis pigmentosa: This is a group of genetic eye disorders that affect the functioning of the retina. Retinitis pigmentosa causes progressive vision loss, eventually leading to blindness in some cases.

Levels of Vision Loss

Vision loss can be categorized into different levels, depending on the severity of the visual impairment. Some common levels of vision loss include:

• Mild vision loss: This level of vision loss may cause difficulty with certain tasks, such as reading small print or seeing objects in low-light conditions. Glasses or magnifying lenses may help with these tasks.
• Moderate vision loss: At this stage, vision loss starts to significantly impact daily activities. Low vision aids like magnifiers and electronic devices can help individuals with moderate vision loss to better navigate their environment.
• Severe vision loss: Severe vision loss or legal blindness occurs when a person’s visual acuity is 20/200 or worse, or they have a severely limited visual field. In these cases, low vision aids and rehabilitation services play a crucial role in helping individuals maintain independence and quality of life.
• Profound vision loss: This level of vision loss involves near-total blindness, and the person might only be able to perceive light and some basic shapes. Rehabilitation services, orientation and mobility training, and non-visual aids like talking devices, textured labels, and assistive technology are vital for those with profound vision loss to live a fulfilling life.
